- CARPET-LINING.

SPECIFICATION forming part of Letters Patent No. 264,889, datedSeptember 26, 1882. Application filed February 11, 1882. (Specimens) Toall whom it may concern Be it known that I, PUTNAM W. LOGKE, of Paris,county of Oxford, State of Maine, have invented a New Article ofManufacture for Carpet-Linings, of which the following is aspecification.

The object of this invention is to utilize the.

the cedar-bark,and, passing it through a ropecutter or hard-stockcutter, reduce the bark to short, small chips. Then putting these chipsinto a stuff-chest, I cause steam to be admitted, subjecting them to itsoperation for from one to three hours, according to the condition of thebark, whether frozen or otherwise. I then put the material into abeating-engine, using cold or warm water, according to the season of theyear, where it remains from two to four hours. These processes reducethe material to a fine, tough, fibrous pulp or felt. This pulp or feltis then passed over a cylinder or Fourdrinier machine, making acontinuous sheet of. any desired length. Then these sheets are placedover the requisite number of 0 driers to dry them properly andperfectly, which is governed by the thickness of the sheet. Thence theyare passed through hot or cold calendars, producing a soft, perfectfinish.

A strong, durable sheathing-felting may be 5 made of this bark by mixingcotton waste or hemp therewith in the process of manufacture.

I am aware that carpet-linings composed of cedar-wood or cedar-wood andother ingredients are not new.

Having described myinvention, whatIclairn as new, and desire to secureby Letters Patent, 1s

1. As a new article of manufacture, a cedarfelt carpet-lining consistingof cedar-bark pre- 4 5 pared as described, and for the purpose setforth.

2. As a new article of manufacture, a felt composed of cedar-bark andcotton-waste, sub stantially as described.
